When officers spoke to him and obtained his details, they found that his phone number was the same as that of a drugs line in Aylesbury that had been recently established.

Dryden-Allen was arrested on suspicion of being concerned in the supply of class A drugs.

During the interview he admitted to having a quantity of class A drugs ‘secreted within his person’, police said in a statement.

These were removed and found to be 40 wraps of crack cocaine and a large package of heroin.

Dryden-Allen was charged on the same day.

He appeared at High Wycombe Magistrates’ Court on Wednesday where he pleaded guilty to to one count of possession with intent to supply a controlled drug of Class A - crack cocaine and one count of possession with intent to supply a controlled drug of class A - heroin.

He was bailed to appear at Aylesbury Crown Court for sentencing at a date to be confirmed.
